Cennick founded the church at Kilwarlin, in 1755 and today you can stand under "Cennick's Tree" in the graveyard.

Four years later a small plot of land was bought adjacent to the Church to serve as a graveyard. During the early years of the Church's existence it had about 80 members and its own Minister. But by 1813 numbers had declined and by 1834 the church was in ruins, the manse was uninhabitable and the grounds were like a wilderness. The congregation now numbered just six elderly people.
